How to get more air circulation under the hood?
I am looking for the most cost effective way to encourage more air circulation under the hood to lower temps a bit.
It feels like a heat wave every time I open the hood now that I have my new manifold installed and it isn't even the summer yet!
There are a few options I know of; hoods, under skid pans, air deflectors, grill inserts, supplement fans, ect.
Which option is going to provide the biggest bang for the buck

i got an idea from looking at my friends ferrari to get more air to the engine in any car. the ferrari had vents inside the wheel well in the rear (where the engine is) with like a small mesh screen over the inside of it. what if you drilled out a few holes and put some screen on the inside of it or went to the hardware store and got some vents to put on the inside of your wheel well.

All good suggestions, I have a feeling the best way is to use an after market hood w/ scoop in conjunction with the vented skid pan.
However I am shying away from hoods over the price and bolt on hood scoops mostly over the tackiness I also like my foggies!
I think I am going to look at either some custom ducting or ways to deflect air more efficiently to start.

This sounds good, any chance you have some photo examples handy?

sorry i dont.
it was a technical performance method with a bunch of physics involved in help explaining why it was better getting air to flow bottom to top.
also, why do u really need to be concerned with underhood temps? when the car is moving it does not get as hot vs. at a standstill. If u want to reduce radiating heat from the manifold, get it coated. This would be the better route of doing it.
I recommend swaintech.com. Best in the business imo, whether it be exhaust manifolds, intake manis, combustion chambers, etc etc. i've tried polydyn, jethot, and HPC. none compares to swaintech.
When i first installed the turbo, underhood temps were unbearable. i got the manifold, exhaust side, and downpipe coated with Polydyn/HPC/Jethot (all similar stuff to each other btw). It helped only a little. So i tried out swaintech. BAAM, underhood temps drastically decreased (a bit cooler than stock). I everything is so much cooler than it was before.

I can't really afford to send off my header for coating, both from a cost side and a logistical side. I need my car for daily driving.
I am wondering if I can get away with using some header wrap
I also have some idea's on how to create an air ram from below. I will have a closer look this weekend to see how feesible it is.
So much cost!! Plus I will loose my stealthy stock look that keeps the 5.0 off my back.

Damn, I am out of time. This seems cheap and easy, will give it a try before I hit the course tommorow in +29 weather.... gulp
